Just wanted to give big thanks to Ray @Double R Diesel. I purchased an MM3 package, complete with Ray's tunes, EGR delete kit and 5" Flo_Pro TBE. Even running the mild tunes, it doesn't even feel like the same truck. Excellent spooling much-improved throttle response and numerous other improvements. No more lugging thanks to the included 68RFE tuning. Truck sounds awesome and runs even better! Ray personally called me and answered all of my questions and even walked me through getting everything set up. Best customer service I have ever experienced. Highly recommended! Thanks again Ray!
